The Bomag 05743400 Catalytic Converter Gasket is a genuine OEM component designed for Bomag BW 100 AD-5, BW 100 AC-5, BW 120 AD-5, BW 120 AC-5, BW 124 DH-5, BW 124 PDH-5, BW 135 AD-5, BW 138 AD-5, and BW 138 AC-5 tandem and single drum rollers. Sourced directly from Bomag, this gasket matches the original specification for a sealed, leak-free interface between the exhaust system and catalytic converter. Choosing an authentic OEM part ensures the exhaust assembly performs as engineered, maintaining emission compliance and protecting the converter itself from premature damage caused by exhaust leaks.
Key Features
- OEM Exhaust Sealing Integrity — manufactured to Bomag's original material and compression tolerances, delivering a gas-tight seal at the catalytic converter joint under sustained heat and vibration
- Direct Drop-In Replacement — matches the original mounting pattern and flange dimensions, installing straight onto the exhaust assembly without modification
- Broad Tandem and Single Drum Roller Coverage — fits BW 100 AD-5, BW 100 AC-5, BW 120 AD-5, BW 120 AC-5, BW 135 AD-5, BW 138 AD-5, BW 138 AC-5 tandem rollers and BW 124 DH-5, BW 124 PDH-5 single drum rollers
- Emission System Protection — a correctly sealed gasket prevents hot exhaust gases from bypassing the catalytic converter, preserving converter efficiency and helping the machine meet applicable exhaust emission standards
- Verified by Part Number 05743400 — confirm fitment using the Bomag OEM part number 05743400 before ordering to ensure you receive the correct gasket for your specific machine variant
The catalytic converter gasket forms the sealing interface between the exhaust pipe or manifold and the catalytic converter housing, preventing combustion gases from escaping before they are treated. When this gasket fails or burns through, exhaust gases can leak at the joint, reducing converter efficiency, producing unusual exhaust odors, and potentially triggering emission-related fault codes that take the machine out of service. Replacing a worn catalytic converter gasket promptly keeps the exhaust after-treatment system functioning as designed and protects the more costly converter from thermal stress caused by uncontrolled gas bypass.
